Hi Bertrand,

I think some files must have been missing in that update
for you to see this misbehavior. As it happens, I've just
posted yet another update, with a few changes unrelated to
UCAC-3. (You can 'sync' ASCOM scopes, and I swapped in SDSS7
in place of SDSS6.) But I'm pretty sure that all files are
now present, so the problem should go away.

What happened was that for a while, the "official" way to
number UCAC-3 stars was by their MPOS number. This number,
running up to a bit past 140 million, is apparently intended
for USNO's internal use; it's not really relevant for the rest
of us, best as I can tell. So USNO shifted to a new numbering
scheme, '3UC' plus a three-digit zone number (from 1 to 360),
a '-', plus a six-digit number. So, for example, '3UC314-159265'
would be a valid identifier. ('3U' was already taken, by a
radio catalog.)

When you entered '3UC137-322711', Guide found the right star
with that identifier, but when you clicked on it, you got the
old MPOS number. This is now fixed.
